IMPROVEMENT IN THE MANUFACTURE O-F'FELTED, CLOTH...

Specification forming part of Letters Patent No. 48,157, dated .July 11, 1865.

To all whom it may cancer-n:

Be it known that I, OHARLEs T YOUNG, of Lawrence, in the county of Essex and State'of Massachusetts, have inven ted an Improvement in Felted Cloth; and I do hereby declare that exact description of the said invention.

'My invention relates to a new article of mannfacture termed linen-warp felt-clothj'the :same'being an improvement upon' the felted cloth heretofore known and used.

In the goods of this class heretofore made the fibrous materials of which the cloth is 001m posed are combined together and mixed in the card, several batsor sheets as they come from the card being lapped or placed upon each vother until the requisite thickness is attained. When made' in this way, the cloth, if cut off and examined at the edges, is "found to have the same fibrous structure throughout its thick: ness, and whatever mixture of materials-such, for instance, as wool, hair, cotton, linen, jute,

&e. has been made in the cards is found imiformly distributed through the finished cloth ,or'fabric.

My improved felted cloth is made as follows: The wool or other fibrous substance that is capable of being felted is preparedby the com mon preliminary processes of assortin g, cleansing, picking, and carding," and during the latter process the fiber, in a thin sheet or lliat, is also preparein a card provided with coarse teeth any non-felting substance-snch as vhemp, linen, jute,'manila, China grass, Ste-and wind this fiber in a thin hat or sheet upon a suitable roller. Two rollers containing the woolen fiber and one roller containing the linen fiber 1 are now. soplaced ina frame or holder that as the bats are drawnofi and submitted to the g 7 process of 'feltiug' the non-felting fiber'shall occupy amiddle position inclosed between two bats of-material capable of being felted-that is to say, two bats of woolen fiberform the outside of the fabric and a batof linen fiber the inside, the relative position of the two kinds of fiber remaining the same after the operation of felting, which is performed in the common manner by the use of heat, moisture, and friction."

-For the central-. bat or ,layer I prefer-to .use linen or other long and strongffiber, which, as

.It becomes partially incorporated and mixed with the wool or other felting fiber upon each side of it, serves to strengthen the felted cloth,

these long fibers thus embraced by and interfibers of wool serying'to bindv the parts togctlier'and compensate, to a.

twined among th certan' extent, for the comparatively weak and tender fibers of the wool.

By this description I intend to define my inention as a felted'cloth having- Qlib."'0f its Sm aces composed. of a material capablfbf being elted, and inclosiug or containing at the center a nol'afelting fibrous materialrhaving ion get filaments and of greater strength: than the fibers 'ojilame'nts of which the exterior is composed, i ufacture.

I do not claim any specific mode or plan of felting'orcondensing the bats or layersto form Q a cloth, as this may be effected by manual lahot and by various kinds-of machinery.

What I claim, and desire to secure. by- Letters Patent, iS-

The felted cloth herein described, thesame being a new article of manufacture.
